We all use dumbbells for strength training. Not everyone has room for lots of them at home though. These MESIXI Adjustable Dumbbell can replace 5 weights. They allow quick adjustment from 6.6 to 44lb. This dumbbell has 8 safety locking groves and an anti-slip handle.
You can use this dumbbell set for a wide variety of exercises. More advanced users can always get the 77lb version.
